I read it is an Armenian loanword, but I can't remember where. Well, you are right, I have nothing to say.--Calak (talk) 11:28, 9 August 2018 (UTC)

It could be an Armenian loanword, but from the above dialectal չօք(čʿōkʿ), չօ̈ք(čʿō̈kʿ, “knee”), which could have been easily back-formed within Armenian from չոքել(čʿokʿel, “to kneel”). I do not find Turkish *çok or *çök ‘knee’. --Vahag (talk) 13:13, 9 August 2018 (UTC)
